FAQ

No, the DAO 01 is specifically designed for the older ABB Freelance 2000 system architecture. For modern systems like System 800xA, you would need a corresponding module from the S800 I/O or a similar series.

The external 24 VDC supply is required to power the output stages of the module, providing the necessary current for the 0/4-20mA loops that control the field devices. The internal power consumption is for the module's own logic.

Yes, compatibility depends on the overall system configuration. The label indicates this unit was used with firmware FEA V 04.36. While it may work with other versions, it is always best to check the Freelance 2000 system documentation to ensure compatibility with your controller's firmware version.
